Question 1 Question 2 Question 3 What is thy " of y = sinx + cosx ? x2+1 Given: y Given : y = O a. -sinx + cosx x 2+ 1 O b. sinx + cosx then , y' = \\x2+ 1 Then, y "= ex O c. -cosx -sinx O True O True O d. sinx -Cosx O False O False Question 4 Question 5 cos+x - sin +x Find the 1st derivative of y= For the function y = 2x 4 -4x 2 - 10, cos 2x - sin 2x y' = 8x (x + 1) (x -1 ) O ay' =1 O True O b. NO Answer O False O cy' =-1 O d.y' =0 Question 6 Question 7 If the function is x2 + y2= 5, then what is dx dy dy The - = sec 2x for the function y = \\ sec 2x - 1 dx O a. dx O True O False dy X Ob. dx y Question 8 dy X The 4th order derivative of the function y = In (x2) is O c. No Answer O d. dx y *=x dy O True O False Question 9 Question 10 1 + tan 2x Given: y =xsin -lx +1-x2 = secx Find: y' secx O True Oay' = cos - 1x O False O b. NO Answer Ocy' = xsin ~ x Ody' = sin - 1x
